Description

Technical Field

[0001] The utility model relates to the technical field of busbar high - voltage shunt reactors, and more specifically, to an outdoor connection structure of a busbar high - voltage shunt reactor. Background Technique

[0002] As a mature means of stabilizing voltage, regulating reactive power, limiting latent supply current, increasing the success rate of reclosing, and improving system compensation degree, high - voltage shunt reactors are widely installed in the busbars and lines of ultra - high - voltage and extra - high - voltage transmission systems. A high - voltage shunt reactor is a large - capacity shunt inductor coil with an iron core. In order to ensure the linear working characteristics of the high - voltage shunt reactor, there is usually an air gap in the iron core, and the reactor is not easily saturated. Generally, the turn - to - turn protection of the reactor does not consider the influence of saturation.

[0003] After retrieval, the utility model patent with the publication number of CN213459313U discloses a shunt reactor convenient for wire connection, including a main body. A fixing frame is arranged on the outer surface of the lower end of the main body. A lower base is arranged on the outer surface of the upper end of the fixing frame. Buffer mechanisms are arranged on the outer surfaces of both sides of the lower base. A connecting rod is arranged on the outer surface of the upper end of the lower base. For this shunt reactor convenient for wire connection, with buffer mechanisms and fixing mechanisms, when hoisting and installing, the buffer springs inside the mechanisms can reduce the collision force between the movable inner rod and the ground, preventing the deformation and damage of the fixing frame caused by excessive collision force between the lower base and the ground. The provided fixing mechanism can fix the line connected to the interface in the limit outer shell when the shunt reactor is connected. The tightening degree of the limit strip can be adjusted by rotating the adjustment knob to prevent the wiring from falling off the interface under the action of external force, bringing better application prospects.

[0004] However, the above - mentioned patent still has the following deficiencies: The line tightness is adjusted by squeezing the line with the limit strip, but when the line sways due to wind and rain, it is easy to cause slippage between the limit strip and the line, affecting the line tightness. In addition, the fixing mechanism for fixing the line is directly exposed outside, and it is easily damaged under the influence of the external environment for a long time, affecting its service life. Therefore, we propose an outdoor connection structure of a busbar high - voltage shunt reactor. Content of the Utility Model
